As shown in FIG. 2, the cross-sectional area of the UPS 16 and the UPS 17 is smaller than the occupied area of the support plate 13d. The gravity center positions of the UPS 16 and the UPS 17 are indicated by 16a and 17a. The center of gravity of the storage rack 1 is indicated by 11a. The UPS 16 and UPS 17 are of the same model and have the same weight and the same center of gravity. Accordingly, the UPS 16 and the UPS 17 are disposed so that the gravity center positions 16a and 17a are symmetrically located with respect to the gravity center position 11a. Furthermore, it is desirable that the distances 18 and 19 between the gravity center positions 16a and 17a and the gravity center position 11a be as long as possible. Therefore, it is desirable that the UPS 16 and the UPS 17 be disposed at a position away from the center of gravity position 11 a of the storage rack 1 to the extent that the UPS 16 and the UPS 17 are in contact. The UPS 16 and the UPS 17 have a size of 125 mm to 450 mm in the x direction, 365 mm to 750 mm in the y direction, and a height of 128 mm to 1050 mm in the z direction.

For example, when the power supplied via the UPS 16 stops due to a momentary interruption or the like, Switch to power. In addition, during normal power supply, power from both sides is supplied to the power line 23d.
[0026]
Further, it is desirable that the power supply lines 16b and 17b of the UPSs 16 and 17 are connected to different power supply sources, such as being connected to the first power supply source and the second power supply source, respectively. As a result, even when the power from one power supply source is momentarily interrupted, the power supply from the other power supply source is maintained, so that the other power supply can be backed up. As a result, the reliability of system operation of the communication devices 15a to 15c is improved. The power supply source is not limited to being directly connected to the power line of the power company, but may be connected to the power supply source via a UPS.
[0027]
The UPS 16 and the UPS 17 can supply, for example, a voltage of 90 V or more for 60 to 90 seconds and a current of 50 to 100 A for 60 to 90 seconds.
[0028]
The instantaneous interruption preventing operation using the communication device storage rack according to the embodiment will be described below. Of the two power supply sources, for example, when the power supply from the first power supply source is momentarily interrupted, the voltage supplied to the feeder line 16b is the rated voltage for 0.03-0.2 seconds, for example. The voltage drops from 100V to 90V or less. At this time, by supplying the power charged in the UPS 16, it is possible to supply the same power as that during normal power supply.
[0029]
In addition, during 120 to 300 seconds after the voltage supplied to the power supply line 16b drops to 90V or less, the voltage supplied from the UPS 16 may drop to 90V or less. Even in this case, when the two UPS 16 and UPS 17 are operated, for example, a current of 25 to 50 A is supplied from each of them, so that each communication device 15 a to 15 c can receive a normal power supply, and normally Can be operated.
[0030]
As described above, according to the present embodiment, by installing the UPS in the storage rack that stores the communication device, communication by the communication device is possible even if an instantaneous interruption occurs. In particular, it is possible to continue without having to stop the establishment transaction of stock trading that instantly changes the contents of transactions by installing a communication device that performs online trading of stock trading in the storage rack and receiving backup of UPS. it can. As a result, it is possible to reduce the risk of the occurrence of an inability to deal with stock transactions. Of course, it is possible to mount not only a stock transaction transaction but also a communication device that performs processing using other communication devices. The communication device corresponds to, for example, a router used for WAN (Wide Area Network), a server used for LAN (Local Area Network), and the like.
[0031]
Moreover, although there is a dead space that is not used because the communication device is not mounted in the normal storage rack, according to the present embodiment, it is possible to save space by effectively using such a dead space. In addition, when a communication device that is normally used and is subject to work is placed on the top of the rack by placing a heavy and unusable UPS on the lowest part of the rack. The center of gravity is lowered, and the communication device can be used in a stable state. In addition, by providing a communication device that is likely to be a work target above the lowest portion where the UPS is difficult to work, work on the communication device such as maintenance of the communication device can be easily performed.
[0032]
In addition, by installing two UPSs and adopting a mutual backup system with two units, even if the power supply on one UPS side is interrupted and power supply cannot be performed only by backup with that UPS, two UPSs can be installed. By operating, power can be supplied to the communication device, and the reliability of operation of the communication device is further improved.
[0033]
